Mid point of A(2, 0), B(0, 2) is
(0, 2)
(2, 0)
(1, 1)
(2, 2)

General form of equation of line is ——————-
ax + y = c
ax + by + c = 0
x + y + c = 0
none

If m1= m2, then both lines will be
Perpendicular
Concurrent
Non-coplanar
Parallel

Two lines a1x+ b1y + c1 0 and a2x b2y + c2 = 0 are parallel if and only if;
None of these
a1/b2 = a2/b1
a1/a2 =b1/b2
a1/b1 = a2/b2

if (x,y) are the coordinates of a point pthen the first component of this pair is called:
None of these
abscissa
y-coordinate
Ordinate

In centre
Centroid
Circumcentre
Orthocentre

(8, 2)
(-2, 1)
(0, 0)
(4, 1)

Every homogeneous equation ax2+ 2hxy + by2= 0 represents two real line passes through (0, 0) if
Both b and c
h2> ab
h2– ab > 0
h2-ab > 0

If A(x1,y1) & B(x2,y2) then ?((x1-x2)2)+(y1-y2)2 is called:
